[Samba] can't add DC to AD domain

[Marco Coli]

Hello,

I have a Win2012 (not R2) server with AD schema 56.

I thought it shoudn't be a problem to add a Samba4 DC, but I have the
following error:
DsAddEntry failed with status WERR_ACCESS_DENIED info (8567,
'WERR_DS_INCOMPATIBLE_VERSION')

Are there workarounds?

Thank you
